I believe there are 3 separate faults here:
1. Rear sinking on engine start is usually down to the rear anti-sink sphere being flat. This sphere is located in the centre at the rear of the car.
2. Suspension running at max is usually down to the plastic link between the anti-roll bar and height corrector failing. It may be possible to re-locate this, but it having popped off once it is likely to do it again, so needs to be renewed.
3. Regular ticking is most likely the accumulator sphere being flat (located on the engine).
WARNING: Do NOT crawl under the car whilst it is supported by the suspension only - it is liable to drop suddenly and sqaush you (especially if you are tinkering with the suspension). Use axle stands, or ramps, or a proper lift.

I suspect that the front suspension rises when the engine starts. There is clearly an overpressure in the rear suspension. I would first see if lowering the suspension with the control lever makes any difference. If not, I would suspect that the height corrector is stuck in high and I would have a look at the linkage which is known to fail. I see that you are new to the site so I'll give you a piece of obvious advice
well known to those of us who work with height correctors. It goes like this: There are those that work with secure axle stands, there are those who work with ramps, there are those that work with vehicle hoists and there are DEAD PEOPLE.

Read the thread a little further down on Xantia rear suspension: Our most experienced sorceror makes a convincing case for a ruptured anti sink sphere at the back and a suspect accumulator sphere at the front; about £40 worth, and he usually knows what he's talking about, whatever I may think to the contrary:-)
